Working With HFC-134A (R-134A)

WARNING: This page is about a different car, the 2016 Infiniti QX60. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
  • CFC - 12 (R - 12) refrigerant and HFC - 134a (R - 134a) refrigerant are not compatible. Compressor malfunction is likely to occur if the refrigerants are mixed, refer to CONTAMINATED REFRIGERANT  below. To determine the purity of HFC - 134a (R - 134a) in the vehicle and recovery tank, use Refrigerant recovery/recycling recharging equipment and Refrigerant Identifier.
  • Use only specified oil for the HFC - 134a (R - 134a) A/C system and HFC - 134a (R - 134a) components. Compressor malfunction is likely to occur if oil other than that specified is used.
  • The specified HFC - 134a (R - 134a) oil rapidly absorbs moisture from the atmosphere. The following handling precautions must be observed:
    1. Cap (seal) the component immediately to minimize the entry of moisture from the atmosphere when removing refrigerant components from a vehicle.
    2. Do not remove the caps (unseal) until just before connecting the components when installing refrigerant components to a vehicle. Connect all refrigerant loop components as quickly as possible to minimize the entry of moisture into system.
    3. Use only the specified oil from a sealed container. Reseal containers of oil immediately. Oil becomes moisture saturated and should not be used without proper sealing.
    4. Do not allow oil to come in contact with styrene foam parts. Damage may result.
